DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] A preferred embodiment of a turning control device for a virtual stationary bike in the present invention, as shown in FIGS. 1 and 2, includes a bile body 10, a video monitor 20 positioned on a front side of the bike body 10, a computer 30 having a program (in this description the computer is independent, but the program can beset in the bike body or in the video monitor 20), and the program is driven by a flywheel of bike body 10 so that the video monitor can show the image of the rider on the bike moving on a road The bike body 10 includes a movable handle 101 having a vertical rod 102, and the lower end of the vertical rod 102 formed as an inner rod 104 fitting in a front cylinder 103 of the bike body 10 and free to turn around with the handle 101. Further a non-circular transmitting rod 105 is provided to extend down from the lower end of the inner rod 104 as shown in FIGS. 3 and 4.

[0015] The front cylinder 103 has its lower end fixed with an upper cover 11 of a control case 1, which consists of the upper cover 11 and a bottom cover 12. The upper cover 11 has a center hole 111 for the non-circular transmitting rod 1-5 to fit in.

[0016] The control case 1 shown in FIGS. 3 has an output terminal 214 connected to the sensor 2 of the computer 30 and the upper cover 11 further has plural screw receivers 112 provided to protruded own from the bottom surface to screw together with the bottom cover 12 provided with plural support rings 121 for screws 122 to pass through.

[0017] The sensor 2 consists of two—one an upper and the other a lower—circuit boards 21 symmetrically held together and a proper gap is formed between the two circuit boards 21. A plurality of light emitting electronic elements 212 are fixed on an upper surface of the upper circuit board 212 and on a lower surface of the lower circuit board 212 to respectively facing each other.

[0018] The output terminal 214 extends out of the control case 1 from a left end of the upper circuit board 21 for transmitting the signal from the electronic elements 212, as shown in FIG. 4. Further, a hole 215 is bored respectively in the two circuit boards 21 near the right side of the electronic elements 212, and a fan-shaped shade plate 22 is placed between the two circuit boards 21, also referring to FIG. 6, having a non-circular hole 221 bored in a small sized portion and aligned to the holes 215 in the two circuit boards 21 fro an insert connect post 23 to insert therein. The insert connect post 23 has a non-circular groove 231 formed in an upper surface to conform to the shape of the transmitting rod 105 and anon-circular block 232 with a threaded hole 233 formed in a lower end to suit to the non-circular hole 221 of the shade plate 22. Further, a short round post 24 inserts in the hole 215 of the lower circuit board 21 from under, having an insert groove 241 of the same shape as the insert block 232 on an upper surface and a through hole 242 aligned to the threaded hole 233 of the insert connect post 23. The fan- shaped shade plate 22 further has a plurality of non-circular holes and slots 222 of different sizes arranged in several concentric circles in the fan-shaped portion of the fan-shaped shade plate 22, as shown in FIG. 5, and there are 16 holes and slots 222 illustrated in this embodiment.

[0019] Assembly of the control case 1 and the sensor 2 is shown in FIG. 4, with the shade plate 22 positioned between the upper and the lower circuit board 21, and with the engage hole 221 aligned to the hole 215 of the two circuit boards 21. Then the fan-shaped shade plate 22 is positioned to face to the electronic elements 212, and the insert connect post 23 is inserted through the hole 215 of the circuit boards 21 from upside, with the insert block 232 passing through the non-circular engage hole 221 of the shade plate 22. Then the short round post 24 passes through the hole 215 of the lower circuit board 21 from under, letting the insert block 232 of the insert connect post 23 fit in a fit hole 241 of the short round post 24. Lastly, a screw 243 passes through the through hole 242 of the short round post 24, screwing with the screw hole 233 of the insert connect post 23, with the shade plate 22 clasped between the insert connect post 23 and the short round post 24 and also between the upper and the lower circuit board 21, and with the shade plate 22 having its upper and the bottom side not contacting the upper and the lower circuit board 21 separated with a proper distance. Thus the sensor 2 is completed in assembly.

[0020] Next, the sensor 2 is placed on the bottom cover 12 of the control case 1, letting the round hole 211 of the circuit boards 21 aligned to the support rings 121 on the lower cover 12, and then the upper cover 11 is closed on the lower cover 12, with the screw receivers 112 passing through the relative round holes 211 of the two circuit boards 21 and aligned to the support rings 121 of the lower cover 12. Lastly, the screws 122 pass through the support rings 121 and screw with the screw receivers 112 of the upper cover 11, fixing firmly the sensor 2 in the control case 1, with the insert hole 231 of the insert connect post 23 of the sensor 2 just aligned to the center insert hole 111 of the upper cover 11.

[0021] Next, as shown in FIG. 4, the control case 1 is fixed with a lower end of the cylinder 103, in which the inner rod 104 of the vertical rod 102 of the handle 101 is inserted. And the transmitting rod 105 inserts in the center hole 111 of the upper cover 11 and also in the insert hole 231 of the insert connect post 23. The output terminal 214 of the sensor 2 is connected to the computer 30 to send signals emitted by the electronic elements 212 to the computer 30. Consequently, when the handle 101 of the stationary bike 10 is turned right or left, the transmitting rod 105 rotated together with the insert connect rod 23 and the short round post 24, and the fan-shaped shade plate 22 rotates eccentrically at the position between the two circuit boards 21 synchronously. The scope of rotation of the shade plate 22 is restricted between two of the screw receivers 112, as shown in FIG. 5, and in other words, when the shade plate 22 rotates to contact the be stopped by any of the screw receivers 112, the shade plate 22 rotates reversibly, not moving beyond the limit.

[0022] Therefore, in using the stationary bike 10, the flywheel may activate the video monitor show image of a user on the bike moving ahead on a road, and the user may move the handle 101 in the same direction of the winding road, with the fan-shaped portion of the shade plate 22 moving together with the handle 101 synchronously. Then the lights emitted by the upper and the lower electronic elements 212 pass through the holes and the slots 222 of the shade plate 22, forming the location of a signal (or the location of the lights of the electronic elements 121 shaded) also altering so that the output signal of the sensor 2 also alters. When the computer program receives different signals of the location of the image of the user and the bike on the road on the video monitor may move to the left side of the road, and moves back to the original location in case of the handle 101 is moved back in the straight position. So a user can change the location of him and the bike at any time, as if the user virtually rides on a bike, getting rod of the monotonous feeling of the conventional computer program the conventional stationary bike has, always keeping the same location without movement on the video monitor.

[0023] As for design of the shade plate 22, as shown in FIGS. 6 and 7, its angle, its size and the positions are minutely calculated and arranged according to the coding mode of Fray. As shown in FIG. 7, the evolving diagram of the shade plate 22, rotation of the shade plate 22 can produce 0-31 modes of the five holes and slots 222, 32 modes in total. In other words, the rotation of the shade plate 22 in shading the lights emitted by the relative electronic elements 212 can produce 32 kinds of different signals to be sent to the computer program to let the image of the user and the bike on a road on the video monitor may change in 32 different ways. And in order to let every way have a buffer area, every way value is set 3 degrees, 96 degrees in total, with the angle between the outer edge of the outer most hole 222 and the center-line being 96 degrees. The shade plate 22 has an angle of 106 degrees. However, these values may change according to different designs.

[0024] The invention has the following advantages, as can be understood from the aforesaid description.

[0025] 1. A user can utilize movement of the handle 101 to change the image of the user and the bike running on a road on the video monitor, having freshness compared with the conventional computer program used in the conventional stationary bike, with some obstacles (such as a small water pool or stone placed on a road) for the user to avoid and feel as if he was really running on a bike.

[0026] 2. The sensor makes use of shading signal lights emitted by the electronic elements 212, having no contact points in the structure, nor giving rise to resistance change or mechanical wear, not affected by voltage change, and the shade plate 122 has the holes and slots 222 arranged to be located by using Fray's code so that interrupted codes or double codes may not happen.

[0027] 3. The sensor 2 is fixed firmly between the upper and the lower circuit board 21 and the shade plate 22, and then combined in the control case 1, so it can be assembled with a mold.

[0028] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and the scope of the invention.
